MEGA EFI-adapter harness

This Bus Interface Module is designed to read engine information from specific MEGASQUIRT EFI kits. These kits

include: Megasquirt-2, Microsquirt, MSPNP2, Microsquirt-module based ECUs with firmware MS2/Extra 3.4.x or later,

Megasquirt-3, MS3-Pro, MS3-Gold, MSPNP-Pro, MS3-Pro-module based ECUs with firmware MS3 1.4.x or later. The module

is connected to the MEGA through the CAN-bus CAN H and CAN L on the MEGASQUIRT harness.

There are two interface (I/O) ports on the module. Either one can be connected to the gauge system or to another

module, allowing several units to be daisy chained together. Do not connect the I/O port to anything other than a Dakota

Digital gauge or BIM. Do not mount the module in the engine compartment; it should be mounted in interior of the vehicle.

The information that is available from the unit depends on the EFI module programming and add-ons. The possible values

are: engine RPM, vehicle speed, engine coolant temperature, intake/manifold air temperature, oil pressure, fuel pressure,

average A/F ratio and boost.

Available readings: RPM, engine temp, intake/manifold temp, fuel pressure, A/F ratio, vehicle speed, oil

pressure, boost/vacuum

• CAN-Bus/Testmodes -> CAN Realtime Data

Broadcasting

• Set Enable realtime data broadcasting over

CAN to "On"

• To enable boost CAN output set “02: Baro,

MAP, MAT, CLT” to ‘ON’(MS2)/50Hz(MS3)

• To enable engine oil pressure CAN output

set “13: sensors 1,2,3,4” to

‘ON’(MS2)/50Hz(MS3)

MAN #650636A

EFI engine oil pressure input

This module is programmed to monitor an engine oil pressure sensor that is connected to ‘Generic sensor input 1’ or ‘Generic

sensor input 2’. If you wish to enable this reading you must enable the  (engine oil pressure) option through the setup menu.

With the unit off, press and hold the button on the BIM. Cycle the ignition to the on position then release the button. Press and

release the button until  is displayed. Press and hold to enter the menu. Press and release the button until (input

1)or (input 2) is shown. Press and hold to select which input your sensor is connected to.

EFI boost

This module is programmed to monitor boost(PSI) data from the MAP sensor. To enable this feature, you must enable the 

(boost) option through the setup menu. With the unit off, press and hold the button on the BIM. Cycle the ignition to the on

position then release the button. Press and release the button until  (boost) is displayed. Press and hold to enter the menu.

Press and release the button until  is shown. Press and hold to select.

Display data usage

The following readings can each be used in place of dedicated sending units to the gauge control unit. These are individually

selectable in the display system gauge setup menus.

*Some gauge features require a minimum software revision or higher to be supported:

Troubleshooting quick tips:

While the BIM is operating, the dot in the upper left corner of the display will indicate the status. On steady indicates it is

powered up but not receiving any BIM bus activity. Flashing indicates it is communicating on the BIM bus.

If the display shows “” then it is scanning to try and communicate with the EFI system bus but cannot get an answer. To see

the sensor and channel status on the BIM display, press and hold the switch. The display will cycle through several screens.

The first will show the bus type (“” MEGASQUIRT EFI). The next screens will indicate which (if any) extended data is

available: “” for intake/manifold temp, “” for engine oil pressure.

To set or change the ID number:

The ID will not normally need to be changed. The fuel PSI and A/F ratio readings both use bus ID’s so if you have other BIM

units connected along with this one there is a chance of ID conflicts. This can easily be resolved. If fuel PSI or A/F ratio is not

showing up in the BIM setup menu on your system you may need to resolve an ID conflict. The following procedure will allow the

BIM-01-2 to automatically select a new, unused ID.

• Hold the switch on BIM while turning the key on. The BIM will show the current software code.

• Release the switch.

• Press and release the switch until “” is shown on the display.

• Press and hold. “” will be shown while the BIM is scanning the bus for other BIM units.

• When you see “” shown on the display release the switch.

• The BIM unit will now go back to normal operation.

HDX TIP: Intake/manifold air temp, Fuel PSI, boost and A/F ratio will be displayed in the group screens if activated through the displays>>group set

menu setup.
